Combinational treatment of kinase inhibitors induces the similar phenotype produced by PP1. All images are lateral view with dorsal to the top and anterior to the left. The combinational treatment of Dasatinib (D) or U0126 (U) with Sunitinib (SU),PTK787 (PTK), or ZM323881 (Z) resulted in the shrinkage of dorsal aorta.

A, Tumour growth curves from the initial sunitinib drug trials, with endpoint set at 1300 mm³ (mean ± SEM ). Measurements begin one week after tumour inoculation and on the day sunitinib treatment began. Subsequent experimental endpoints were set based on these growth curves and their intersections with this data are shown. B, histogram plot showing the distribution of tumour sizes at day 8 of treatment. Sunitinib treated tumours exceeding 250 mm³ in size were identified as falling into the non-responsive cohort. Sunitinib treatment significantly retards growth of responsive tumours.

Sunitinib decreases FLT-3 and RET phosphor ylation but increases ERK phosphorylation in a time-dependent manner. H295R and SW13 cells were treated with sunitinib (10 nM) for various time points as indi-cated. Cell lysates were prepared and phospho-FLT-3, RET, and ERK levels were monitored by Western Blot-ting. Re-probing against FLT-3, RET, and ERK was done to ensure equal protein loading.

Sunitinib or PD98059 decreases cell proliferation in a dose-dependent manner. H295R and SW13 cells were treated with various concentration of sunitinib or PD98059 for 48 hours as indicated. Treated cells were subjected to the MTS proliferation assay. Similar experiments were repeated 3 times. Histograms represent relative % of OD490 nm absorbance (* P < .05). All data are relative multiples of expression compared with untreated cells. The data are representative of three experiments and are expressed as the mean ?SE.

Autophagic activation in sunitinib- and sorafenib- but not AZD6244-treated cells. Medullary thyroid cancer-1.1 (MTC-1.1; A) and TT ( B) cells were treated with dimethyl sulfoxide (DMSO), sunitinib (50 nM), sorafenib (10 nM), AZD6244 (30 nM), or everolimus (20 nM) for 48 hours. Cell lysates were prepared, and light chain 3 (LC3)-I and -II cleaved caspase-3 protein levels were monitored by Western blotting. Reprobing against actin was per formed to ensure equal protein loading. ( C ) MTC-1.1 and TT cells were transiently transfected with autophagy protein 5 (Atg-5) small inter fering RNA. Transfection with scrambled small inter fering RNA was used as a control. After transfection, cells with and without Atg-5 knockdown were exposed to DMSO or 20 nM of everolimus for 48 hours. Cell lysates were pre- pared and LC3-I and -II protein expression levels were monitored by Western blotting. Reprobing against Atg-5 was per formed to monitor Atg-5 knockdown efficiency. Reprobing against actin was per formed to ensure equal protein.

Autophagy inhibition blocks the antiproliferative effects of sunitinib and sorafenib but not AZD6244. Medullary thyroid cancer–1.1 (MTC-1.1) and TT cells were transfected transiently with scrambled or autophagy protein 5 (Atg-5) small inter fering RNA. After transfection, cells with and without Atg-5 knockdown were exposed to sunitinib (50 nM), sorafenib (10 nM), and AZD6244 (30 nM) for 48 hours. Treated cells were subjected to a 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium proliferation assay. Similar experiments were repeated 3 times. Histograms represent the relative percent of OD490 nM absorbance. The asterisk indicates significance versus scrambled small inter fering RNA–treated control ( P < .05). All data are relative multiples of expression compared to untreated cells. The data are representative of 3 experiments and are expressed as the mean ± the standard error.

Sunitinib limits the colonial growth of HT-29 by downregulating HIF-1a. (A) The number and size of colonies formed in soft agar. The numbers of small colonies (<50 μm diameter) were not different among conditions of a serial concentration of sunitinib. On the contrary, large colonies (>50 μm diameter) disappeared after incubation with sunitinib. Each point represents the mean and SD from four separate experiments. (B) HIF-1a expression and hypoxia within HT-29 colony. After colonies grew for 4 weeks, HIF-1a and hypoxia were visualized by immunofluoroscence staining. Bar = 20 μm.

2. Sunitinib downregulates HIF-1a. (A) Dose-dependent repression of HIF-1a protein level by sunitinib in HT-29. HT-29 cells were incubated under normoxic (N) or hypoxic (H) conditions in the presence of sunitinib for 24 h. HIF-1a and ARNT proteins in total cell lysates were analyzed by Western blotting. (B) Sunitinib attenuates the hypoxic induction of HIF-1 target genes. RNAs were isolated from HT-29 cells subjected to normoxia (N) or hypoxia (H) in the presence of sunitinib for 16 h. The mRNAs of HIF-1a and its target genes were analyzed by RT-PCR and autoradiography. PGK1 indicates phosphoglycerate kinase 1; PDK1, pyruvate dyhydrogenase kinase 1; CAIX, carbonic anhydrase IX. (C) Sunitinib-induced HIF-1 inhibition. Epo-enhancer and b- galactosidase reporter plasmids were co-transfected into HEK293 cells. After 16 h incubation, luciferase and b-galactosidase activities were measured. *P < .05 versus the hypoxic control.

Sunitinib inhibits 50-UTR-dependent translation of HIF-1a. (A) 50 cap-dependent translational activity of HIF-1a. The luciferase reporter plasmid contains the HIF-1a 50-UTR segment between the tk promoter and the luciferase gene. HT-29 cells were co-transfected with the reporter plasmid (8 lg per 100-mm dish) and the b-gal plasmid (4 μg). After 16 h incubation under normoxic or hypoxic conditions with sunitinib, cells were lysed and subjected to luciferase assay. *P < .05 versus the hypoxic control. (B) IRES-dependent translational activity of HIF-1a. The luciferase reporter plasmid contains the HIF-1a 50-UTR segment between the GFP gene and the luciferase gene. HT-29 cells were co-transfected with the reporter plasmid (8 μg) and the b-gal plasmid (4 μg). *P < .05 versus the hypoxic control. (C) Sunitinib inhibits phosphorylation of Akt. After 8 h incubation under hypoxic condition with sunitinib, HT-29 cells were lysed and subjected to Western blotting. (D) Sunitinib suppresses HIF-1a in VHL-null RCC4 cells.
